Nuclear Metals Superfund Site

In Concord, Massachusetts, near the border with Acton, there is a federal Superfund site — the Nuclear Metals, Inc. site — that is threatening Acton’s water supply through contamination of Acton’s Assabet wells. The main concern is 1,4-Dioxane, a probable human carcinogen that moves readily through groundwater. These are the same wells that were contaminated by the WR Grace Superfund site). You will see this same Superfund site called “Starmet” and “2229 Main Street.”
